DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film unit with a lens (film-integrated camera) which is pre-loaded with an unexposed roll-shaped photographic film and has an exposure function for photographing, and more particularly to an outer box thereof. .

[0002]

2. Description of the Related Art Film units with a lens are widely used for taking a picture when a user does not carry a camera. This is a cartridge in which a patrone and an unexposed film are previously loaded in a dark box-shaped main body provided with a photographing lens and a shutter, and are widely marketed at film stores and the like.

[0003] The film unit with the lens, after taking a picture, requests development to a film unit and a print development laboratory in a state where the film is built in. At the developing station, the photographed film is taken out from the film unit and subjected to a developing process. Then, the film unit main body is discarded or partially recycled for use in a developing laboratory.

Conventionally, in order to provide this lens-equipped film unit at a low cost, a plastic lens is mounted on a plastic-molded black unit main body, and a film and a patrone are built therein.
The unit body is housed in an outer box made of cardboard or the like. This outer box is made of a simple paper carton on which a product name, a usage method, a design, and the like are printed, and forms an outer case of the camera.

[0005]

When a photographed film is taken out of the above-mentioned film unit with a lens in a developing station, the outer box must first be broken to expose the unit body.

In order to process a large number of film units quickly, it is necessary to make the time-consuming operation of removing the unit body from the outer box more efficient.

On the other hand, an empty unit main body from which the back cover is opened from the unit main body and the film in the cartridge is taken out is discarded or reused.

The outer box is torn, discarded, and thrown away when the photographed unit body is taken out, thus wasting resources. Further, since such an outer box is used only once, the material is limited due to the limitation of manufacturing cost, and an inexpensive one is used. For this reason, it has been difficult to improve the aesthetics of the outer box, the grip feeling, the impact resistance, the dust resistance, and the like.

[0009]

According to the present invention, a unit body of a film unit with a lens (a simple camera provided with a photographic lens, a shutter, a finder, a film winding mechanism, etc.) is provided for taking out a photographed film from the unit body. It is an object of the present invention to provide a lens-equipped film unit that can be easily removed from an outer box to quickly take out a film containing a patrone from inside the unit main body, and that the outer box can be reused.

In order to achieve the above object, a film unit with a lens according to the present invention is a film unit with a lens, in which at least a part of a film unit body with a lens in which a roll-shaped photographic film is previously loaded is covered with an outer box. An outer box provided with an elastic locking member which engages with the projecting portion of the lens-fitted film unit main body to lock the outer box, and deforms the locking member to form the lens-fitted film unit. The outer box can be taken out of the main body.

Also, in a lens-fitted film unit in which at least a part of a lens-fitted film unit main body pre-loaded with a roll-shaped photographic film is covered with an outer box, the outer box is provided on the lens-fitted film unit main body. A lens mount having a through hole exposing the finder window, an outer box main body covering the periphery of the lens mount and the finder window, and the outer box main body being connected to a back side of the lens unit-equipped film unit main body; An outer box cover for covering a portion for holding the film unit body with a lens, and in a state where the film unit body with the lens is covered with the outer box, an end of the outer box cover is the outer box.
